[opensuse] Hauppauge DVB-S cards - how to use the MAC address in udev rules?

29 Nov 2012

      On my new mythtv backend, I have two Hauppauge DVB-S cards for satellite
reception.  I would like to assign permanent device names to them using
some udev rules.  The cards do have unique MAC addresses, but afaict,
they are not available through/to udev.  udevadm does not list it, see
below. 

Any suggestions?  (apart from using the adapter_nr argument on the
module).

thanks
Per

# udevadm info --attribute-walk --name /dev/dvb/adapter3/frontend0

Udevadm info starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.
